CheckDigits::M10_002 - compute check digits for CINS (US), SIREN (FR), SIRET (FR)
use Algorithm::CheckDigits; $siret = CheckDigits('siret'); if ($siret->is_valid('73282932000074')) { # do something } $cn = $siret->complete('7328293200007'); # $cn = '73282932000074' $cd = $siret->checkdigit('73282932000074'); # $cd = '4' $bn = $siret->basenumber('73282932000074'); # $bn = '7328293200007'
Beginning right all numbers are weighted alternatively 1 and 2.
The total of the digits of all products is computed.
The sum of step 3 ist taken modulo 10.
The check digit is the difference between 10 and the number from step 3 taken modulo 10.
Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given above.
$number
Returns false otherwise,
The check digit for $number is computed and concatenated to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits and spaces.
Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
Returns the checkdigit of $number if $number has a valid check digit.
None by default.
